The iQue® 3 Advanced Flow Cytometry System — Go from Samples to Actionable Results in Record Time
Traditional flow cytometers have been good at capturing a small number of samples and performing in-depth analysis on either the phenotypes or the captured signals in separate assays due to the wide range of fluorescent signals. This makes it necessary to run separate assays at differing time points, reducing biological relevance and making it difficult to compile and merge the data for interpretation.
The iQue® advanced flow cytometry platform utilizes a fixed wide dynamic range allowing for the collection of both the phenotypes and functional analysis of secreted cytokines simultaneously, eliminating the discrepancy of different time points or the need to split samples for subsequent analysis.

iQue® Specifications & Optical Configurations
The iQue® 3 is Available In Multiple Optical Configurations and Flexible Plate Formats
The iQue® 3 flow cytometry platforms come in 3 configurations to address a wide range of experimental applications. The entry level 2 laser iQue® 3 BR system is equipped with a blue and a red laser ideal for applications which do not require many parameters, but, can take advantage of the speed the iQue® platform is famous for.
Two additional 3 laser configurations increase the flexibility and accommodate larger multiplexing needs depending on the specific fluorphores. The iQue® 3 VBR system includes Violet, Blue, and Red lasers, while, the iQue® 3 VYB replaces the red laser with a yellow laser.

Sartorius Flow Cytometry Instrument FAQs
Get answers to the most common questions about about Sartorius flow cytometry instruments including critical information regarding measuring, speed, plate handling, compliance, and more.
Cell or particle size and complexity are the non-fluorescent measurements along with fluorescent detection which can be used to identify and quantitate specific proteins both on the surface of cells as well as detection of secreted proteins or signaling molecules.
The iQue® flow cytometer uses a proprietary Air-Gap sampling method which can sample an entire 96 well plate in 5 minutes, or a 384 well plate in 15 minutes. But, the speed doesn’t stop there. The included Forecyt® software makes analysis a breeze by utilizing dynamic plate level data analysis and visualization making quick work of identifying the samples of interest.
Yes. It is compatible with all the major automation vendors systems. An iQue® 3 automation client software license is available allowing the plate handling robot to control the iQue® 3 to load plates, begin a run, and remove plates when the run is completed.
The enhanced rinse station is a smart fluidics system that constantly measures the volume of each buffer or solution to avoid failed runs due to insufficient reagents. It utilizes special cartridges for each fluid which minimize evaporation and can be sealed and placed in the refrigerator when not in use to extend the on-board lifetime when not in use.
